3 The flue gas approaches in use today require clean-up of the NO x and SO 2 prior to CO 2 separation. The oxygen route does not. If the sinks are tolerant to NO x and SO 2, we can eliminate separate control steps and sequester the NO x and SO 2 along with the CO 2, resulting in a zero emissions power plant.

Ball milling and subsequent annealing is a simple method for the production of CNTs. Although it is well established that mechanical attrition of this type can lead to fully nano porous microstructures, it was not until a few years ago that CNTs of carbon and boron nitride were produced from these powders by thermal annealing.
